A further object of the invention is to pro vide a laundry machine cylinder which is very simple to assemble and in which the various parts are readily replaceable.

A further object of the invention is to provide a metal wash cylinder in which the'various units are of a uniform size and may knockdown construcbe used in a cylinder of a desired length and is of unique construction and formedwith inside supporting bands. j

A further object of the invention isto provide a metal wash cylinder in which all of are cast and in which no machine workis required. l

A further object of the invention is to provide a laundry cylinder in which all of the plates making up the outer shell are formed with alternating and reversed notches or recesses and tongues or projections offset and cast in such a way that the members interlock to form a secure joint.' j

A further object of the invention is to provide a sectional laundry cylinder which can be made up with the same rib and plate castings into cylinders of different lengths and diameters.

A further obj eet of the invention is to provide a sectional laundry cylinder, which because of the character of the constituent parts, enables a dealer to keep a large stock in a very compact way in a limited space, facilitates and simplifies packing andshipping eliminates possibility of errors in as- 5, 1926. Serial No. 146,399.

scmbling and does not require the use of special tools or jigs in assemblin A furtherobject of the invention is to provide .a cylinder of the class described which is of very simple construction, is strong and durable and is .well adapted for the purposes described.

. With the above and other objects in view, the invention consists of the improved laundry machine cylinder, and its partsand combinations set forth in the claims, and all equivalents thereof. In the accompanying drawings in which thesame reference characters indicate .same parts in all of the views:

Fig. l is a perspective view'of the improved laundry machine cylinder;

plate shown in Fig. 10.

view of a I Fig. 5 is a fragmentary detail perspective Referring now more particularly to the to accommodate the ribs 11, the ribs being bolted thereto, as shown in Fig. 2.

A rib 11 is shown in detail in Fig. 5 and the same is U-shaped in cross section, and its walls are formed with a plurality of apertures 14. The outer edge portions of the side walls of each rib are also formed with recesses 15 to form joints. 7

The peripheryof the cylinder, except for certainportions reserved for doors, is covered by a plurality of curved plates 16, shown in detail in Figs. 3, 9, 10 and 11. The edge portions of said plates are provided with alternating and reversed recesses 17 and tongues 17 by which means the plates are secured together to form half lap joints and to the ribs 11, as shown in Fig. 1. The plates are also secured by bolts 18 to the rim portions of the heads 10 and 12. Said plates are cast with a plurality of suitably sized and spaced perforations 19.

As shown clearly iii-Figs. i0 and 11, the

perforations 19 are tapered to form funnelshaped openings, being larger .on the inside of the cylinder. It will also be noted that the tapers of the different perforations are graduated from the center outwardly toward both side edges of the plate. That is to say, the outermost walls of the holes outwardly of the medial portion of the plate are more tapered than those toward the center of the plate, as indicated at 19. The arrangement of said perforations is such that water may enter. the cylinder with reduced resistance and when clothing within the cylinder strikes the openings, the water is readily drained therefrom and the tapered formation of the openings causes them to act in the manner of scoops when the cylinderis reciprocated.

The compartments within the cylinder are divided by diametrically extending shelves 20. flanged at their edge portions and bolted to the plates 16 and to the heads 12. Said shelvesare also provided with spaced perforations 21. j

The surface ofthe cylinder is arranged with opposed door openings to afford access to the compartments or pockets, and said openings are adapted tobe controlled by doors 2-2. Said doors are slidably mounted between outer strips 28 and inner strips 24 held together by screws Each door is provided with perforations, and is releasably retained in closed position by a single loci: or catch 26 mounted on the adjacent rib 11. i s

It will thus be seen that the cylinder, illnstrated by Figs. 1, 2, 3, i and 5, is of the closed type ofcy'linder washer, and is composed primarily of heads, ribs and plates suitably jointed together, the units being arranged for quick assembly and the ready replacement of parts.

In Figs. 6, 7 and 8, an open type of cyl trolled by doors 22 slidably mounted between strips, as in the main form of the invention, and releasably held in'closed position by locks 26.

The interior of the cylinder, in this form of the invention, is entirely open and uninterrupted. However, the membors are braced at intermediate points by sections 27 bolted to the ribs 11 and to the plates 16 where they contact with the same.

From the foregoing description, it will be seen that the improved cylinder for laundry machines is of very simple and novel con struction, and is well adapted for the purposes described.

What I claim as my invention is:

1. As a new article of manufacture, a plate for reciprocating cylinders having a plurality of tapered openings, the tapers of said openings being graduated as to inclination toward the side edges of the plate, to act on a liquid when the plate is moved, the metal adjacent the openings being non-protrudi'ng so that the plate surfaces are smooth.

2. A laundry machine cylinder, comprising a pluralityof heads, the periphery of said heads being to med with U-shaped recesses, ribs, U-shaped in cross-section, connecting said heads and detachably mounted in said recesses, the edge portions of the ribs being formed with tongues and grooves, and a plurality of perforated. curved plates interposed between the ribs,

the side edges of said plates being formed with alternating tongues and recesses for engagement with adjacent rib tongues and recesses, and some of said tongues and re cesses engaging the tongues andrecesses of adjacent plates.

3. In a knock-down laundry machine cylinder, a sectional frame consisting of heads and ribs connected together, and a wall composed of sheets raving detachable tongue and groove joint connections with each other and with the ribs, there being a longitudinal joint between a pair of sheets intermediate a pair of ribs.

In testimony whereof, I affix my signa ture.

JOHN JORGENSON.
